layer23: Avoid mempcy with NULL src
Fixes following ASan warning: git/osmocom-bb/src/host/layer23/src/misc/../common/main.c:146:2: runtime error: null pointer passed as argument 2, which is declared to never be null The warning however is harmless since in that case, app_len = 0 and thus size to copy is 0.
